A Global Hartman-Grobman Theorem
Xiaochang Wang
We showed that for any bounded neighborhood of a hyperbolic equilibrium point , there is a transformation which is locally homeomorphism, such that the system is changed into…
Output Feedback Pole Assignment for Transfer Functions with Symmetries
Uwe Helmke, Joachim Rosenthal, Alex Wang
This paper studies the problem of pole assignment for symmetric and Hamiltonian transfer functions. A necessary and sufficient condition for pole assignment by complex symmetric ou…
The Multiplicative Inverse Eigenvalue Problem over an Algebraically Closed Field
Joachim Rosenthal, Xiaochang Wang
Let be a square matrix and let be a monic polynomial of degree . Let be a set of matrices. The multiplicative inverse eigenvalue problem asks for the…
Zero Assignment, Pole Placement and Matrix Extension Problems: A Common Point of View
Meeyoung Kim, Joachim Rosenthal, Xiaochang Alex Wang
The paper studies a general inverse eigenvalue problem which contains as special cases many well studied pole placement and matrix extension problems. It is shown that the studied…
Degree of the generalized Plücker embedding of a Quot scheme and Quantum cohomology
M. S. Ravi, J. Rosenthal, X. Wang
We compute the degree of the generalized Plücker embedding of a Quot scheme over $\PP^1$. The space can also be considered as a compactification of the space of algebra…
